It is the first time that an image of this magnitude has ever been created.

The last record attempt for a London panorama was 80 gigapixels – only a quarter of the size.

Those images were taken from Centrepoint in 2010.

The interactive map invites Londoners to find their favourite places or views and share them with other London lovers.

Photography firm 360Cities said his team had to battle the worst of the British weather to capture the image.

Director Steve Hercher said: "So many unknowns and variables had to be addressed in the planning of this unprecedented shoot, really the first of its kind.

"Software and hardware were pushed to the limits, and rain, wind and other potential stumbling blocks had to be dealt with.

"Our photography team of Jeffrey Martin, Tom Mills and Holger Schulze did an amazing job and not a single individual frame from the more than 48,000 planned was missed."

The team used four Canon EOS 7D cameras to record the images.

Suzi Williams from BT, who sponsored the picture, said: "What better way to capture that remarkable year than with a full panoramic photograph taken from its roof. This isn’t just a world record for the BT Tower, it’s for London and the people who live, work in or visit the capital."
